QPL9057 Flat Gain Amplifiers
Qorvo QPL9057 Flat Gain Amplifiers are designed to provide a flat 2.4dB gain over a wide bandwidth from 1.5GHz to 3.8GHz. These gain amplifiers provide 22.8dB gain, +32dBm OIP3 at a 50mA bias setting and 0.54dB noise figure. The QPL9057 gain amplifiers require five external components to operate from a single positive supply as they are internally matched using a high-performance E-pHEMT process. The single positive supply includes an RF choke, blocking/bypass capacitors, and a bias resistor going to pin 1.
